China FL Series Boiling and Granulating Dryer - Quality Equipment from Reliable Suppliers and Factory
Principle
The powder granule in vessel (fluid bed) appears the state of fluidization. It is pre heated and mixed with clean and heated air. At the same time adhesive is sprayed into the container. It makes some particles become granulating which contains adhesive. Being of unceasing dry through hot air, the moisture in the granulating is evaporated and the adhesive is solidification. The process is carried out continuously. Finally it forms ideal, uniform and porous granules.
Applications
Pharmaceutical industry: granular tablet, granule taken with water, granular capsule.
Foodstuff: cocoa, coffee, milk powder, juice of granule, flavoring and so on.
Other industries: pesticide, feed, fertilizer, pigment, dyestuff and so on.
Drying: for powder or granule damp material.
Coating: granule, pillprotection layer, pigmentation, controlled release, film, or bowels solved coating.

Frequently Asked Questions
How does the FL Boiling and Granulating Dryer work?
The powder granule is placed inside the fluid bed vessel and fluidized by pre-heated, clean air. An adhesive is then sprayed into the container, causing the particles to form aggregates. Continuous dry hot air evaporates the moisture and solidifies the adhesive to form uniform, porous granules.
What are the primary applications of the FL series dryer?
It is widely used in the pharmaceutical industry for tablets and capsule granules, the foodstuff industry for products like coffee, cocoa, and milk powder, and other fields like fertilizers, pesticides, and pigment manufacturing. It is also utilized for drying damp materials and coating applications.
Can the drying temperature be adjusted?
Yes, the operating temperature is fully adjustable, ranging from room temperature up to 120℃, allowing you to customize the process according to the specific properties of your raw materials.
What is the dust collection efficiency of this equipment?
The FL Boiling and Granulating Dryer features a highly efficient collection system with a dust collect rate of ≥99%, ensuring minimum product loss and a clean working environment.
How do I choose the right model for my production needs?
Models range from the laboratory-scale FL-3 (handling 1.5–4.5 kg per batch) up to the large industrial FL-500 (handling 250–750 kg per batch). Selection depends on your desired batch volume, vessel capacity, and processing requirements.
